Iowa, Wisconsin in trouble at the half (UPDATED)

Something is rotten in the state of Indiana, and it's the play of conference leaders on the road. Wisconsin currently trails Purdue 10-6 at the half, and Iowa is tied with Indiana at 6-6.

Purdue has been completely unconcerned with testing Wisconsin's defense deep in the first half, using quick, short throws to move the chains and relying on Dan Dierking to get key first downs. Quarterback Sean Robinson has been surprisingly competent, and he's got a great rapport with Antavian Edison at wideout. Edison caught the only touchdown of the game thus far on a 23-yard catch-and-run, and has five catches for 54 yards on the day; he's the game's leading receiver after two quarters.

[UPDATE, 1:55 p.m.: Wisconsin intercepted Robinson and returned it deep into Purdue territory on the first drive of the second half. After converting a 4th and 1, Wisconsin scored a touchdown and now leads 13-10.]

Meanwhile, the Iowa-Indiana game has been marked by long drives, but no touchdowns; most of the field goals in this game have come in the red zone. In fact, Iowa would be leading 9-6, but kicker Michael Meyer missed a chip shot from 21 yards out late in the first half. Ben Chappell and Ricky Stanzi have each thrown costly interceptions, and each team should feel like it should be leading here in Bloomington.
